Definitions
- the present invention relates to a device for assembling or fitting together two pieces, guaranteeing the exact position and the exact orientation of one of said pieces with respect to the other.
- This device may be used for instance in watch-making for assembling the component parts such as pillar plates, bridges, balance cocks, pallet cocks, stem cocks of the frame of a watch movement, but may also be used generally for any kind of apparatus. 25
- cylindrical reference members pillars, feet, pins
- Such assemblies may be satisfactory if the fitting surfaces are established and rectified with the required precision and care, but these operations are difiicult and expensive.
- the present invention aims at overcoming these drawbacks. It relates to a device for assembling or fitting together two pieces, said device including at least one ball a portion of which engages without side-play a recess of one of the pieces, the other portion of said ball engaging without side-play a recess of the other piece, so as to render both recesses coaxial with each other.
- FIGURES 1, 2 and 3 represent in axial section these three embodiments, respectively.
- FIGURE 1 shows the two pieces to be assembled with each other, which are denoted by the reference numerals 1 and 2, respectively.
- the piece 1 is for instance a pillar plate of a watch and the piece 2 a bridge.
- a recess 3 consisting in the present case of a cylindrical bore.
- a recess 4 consisting here of a cylindrical bore having the same diameter as the bore 3.
- a ball 5 of the same diameter as the bores 3 and 4 is secured by setting it or by caulking it in the bore 3 in such a manner that some more than its half engages said bore 3.
- the piece 2 is thus perfectly guided by the projection of the ball 5, so
- both pieces 1 and 2 are again present.
- the recess made in the piece 1 consists here of a stepped bore including a portion 6 having the same diameter as the ball 5, followed by a portion 7 of less diameter.
- some more than the half of the ball 5 engages the bore 6, 7.
- the ball 5 rests over a small circle on the edge 8 of the bore 7 and is welded to the piece 1 in the recess 6, 7. Welding may be carried out between the ball 5 and the bore 6, or between the ball 5 and the edge 8 or in both places.
- the third embodiment differs from the preceding one in that the recess made in the piece 1 consists of a blind hole 9 of the same diameter as the ball 5.
- the ball 5 is cemented or mounted with friction fit in the hole 9.
- the ball might be simply driven into the recess of the piece 1.
- both recesses consist of blind holes of the same diameter as the ball, it is not necessary to provide fixing means for the ball.
